For the tuning and optimization of mobile applications, user Quality of Experience (QoE) should be closely considered as a key development metric. While previous research has approached application tuning from different perspectives, there has rarely been any sophisticated analysis of QoE at the user interface level. In this paper, we propose QX-probe, a comparative and quantitative QoE analysis tool for application tuning. We define latency, energy, and UI (User Interface) usage information as critical factors for QoE analysis. QX-probe measures these factors at the UI level and provides a range of information for QoE analysis by means of a web-based tool. The usefulness of QX-probe is validated through a number of case studies using real application. Developers should be able to use this tool to identify application tuning points.
